Document Summary
10 reaction sequence converting glucose to 2 3-carbon molecules of pyruvate glucose + 2adp + 2p + 2nad+ >> 2 pyruvate + 2atp + 2nadh + 3 reactions changing glucose into a compound that can be readily cleaved into 3-carbon phosphorylated molecules. 2 of the reactions require use of atp step b - cleavage/rearrangement. 2 reactions break up 6-carbon molecule into 2 3-carbon molecules. 1st of 2 reactions forms g3p and another molecule that turns into g3p through the 2nd reaction substrate-level phosphorylation - 2nd half of glycolysis; makes pyruvate from g3p. 2 electrons, 1 proton transferred from g3p to nad+ to make nadh step d - atp generation. 4 reactions convert g3p to pyruvate, generating 2 atp in total, 4 atp per glucose molecule produced. Co2 acetyl-coa - produced by a large number of metabolic processes. 1 key point for many catabolic processes in eukaryotes used for fatty acid synthesis instead of krebs cycle when atp.
